I started this project because every "free" privacy tool I tried wanted my files, my email, or my credit card. I wanted something I could open and use without asking a stranger to be trustworthy.
So I built it. Then I kept building. Twelve browser tools that run entirely in your tab. Twenty-eight mobile apps that work offline. A free daily to-do list that resets at midnight. None of it has a server that touches your data, because none of it needs one.
If you've ever looked at a "we take your privacy seriously" banner and wondered if you actually had to take their word for it — this is the version where you don't.
